ACOUSTIC FILTER FOR SEPARATION OF PARTICLES OF FLUID DISPERSED SYSTEMS Russian patent published in 2010 - IPC B01D21/28 

FIELD: process engineering.

SUBSTANCE: invention relates to devices intended for separation and concentration of particles of fluid dispersed systems: suspensions in the field of standing acoustic wave, and can be used in biology, medicine and food industry. Proposed filter comprises working chamber with inlet and outlet branch pipes that is arranged in cooling chamber incorporated with cooling fluid circulation system, and ultrasound radiator mounted in cooling chamber. Ultrasound radiator represents a ball segment with its concave surface facing said working chamber. Ball segment base plane runs parallel with working chamber lengthwise central axis and is located at a distance therefrom.

EFFECT: higher efficiency and quality of separation.
